Can you advise where to start or some sort of tutor?
I open those animation tab and dont understand any, lol
1. create a new pose model
2. select the character, go to "custom" and click "create custom", this will create all the poseable controllers (bones) in your character's hierarchy
3. add in your animation sequencer and open it up
4. Select a bone from your character's hierarchy, such as the "Full Torso". In your animation sequencer click the green "+object"
5. click the blue "+Track" button, click transformer, and add in your position and rotation.
you have now added the ability to animate the position and rotation of the torso
6.move the track to any point in the timeline and click the "Add keyframe" diamond icon after adjusting the torso to whatever position/rotation
7. additionally you can click the Curves option at the bottom of the animation sequencer to view the curvature of the values rather than just the keyframes and adjust the curves.
some useful shortcuts
Ctrl+Scroll wheel to zoom in and out
Right Click Drag to move the timeframe around
There should be an official tutorial up at some point
